The circuit 4 outputs the threshold value appropriate to reproduction of a digital code, and the comparator 3 reproduces the digital code. This output of reproduction turns on a light emitting element 9, and this optical output is received by a photodetecting element 1a and amplified 2a. Both circuits 4a and 3a reproduce the digital signals and output it to an output terminal 6a. A through capacitor is used at the part where power supply terminals 5 and 5a and earth terminals 7 and 7a are piercing through shielding cases 10 and 10a. In such a way, the signals are optically transmitted within an optical receiver to secure the high noise resistance characteristics.

Abstract: PURPOSE:To attain signal conversion at ultrahigh speed and ultra broad band by connecting plural signal converters between the input/output terminals of which a sampling signal having the same frequency is applied sequentially at an equal interval in parallel. CONSTITUTION:A broad band analog signal having a frequency up to, e.g., nearly 20MHz is applied to the A/D converters 2, 3, 4 from an input terminal 1. A signal from a reference oscillator 7 whose reference signal is 40MHz is frequency-divided into 1/N (1/4 in this case) by a frequency divider 8 and applied to each clock terminal of flip-flop circuits 9a-9d where shift registers 9 are connected in cascade as a shift clock, and a signal at each output of the 9a- 9d is applied to the corresponding A/D converters 2-5 as a sampling signal. Then the analog signal is converted sequentially into a digital signal by the A/D converters 2-5, converted into a serial digital signal by a parallel/serial converting circuit 6 and extracted to an output terminal 10. That is, the signal conversion equivalent to the A/D conversion with a signal having a sampling frequency of 40MHz directly substantially is attained.
